Abstract: Today's concepts of the fuel cycle intend timt high level nuclear waste produced by nuclear reactors shall be disposed in dem geological forrnations. This idea has been criticized because of the extremly long terms needed to mach an unobjectionable level by radioactive decay. A chemical seperation of isotopes wich very long half-lifes from the waste-stream and a subsequently nuclear transmutation into short living isotopes gives us the possibilty to shorten the time needed for a safe enclosure down to 1000 years. For this period technical barriers are able to guarantee a save enclosure of the waste. From the point of view of savety, non-critical accelerator driven transmutation is a very interesting solution. Protons are accelerated up to high energies and impinge onto a target where they produce a high neutron flux as a result of spallation reactions. These neutrons are necessary for the transmutation of the bong living isotopes. The investigations of this doctoral thesis describe the construction of a proton beam window, which seperates the accelerator vacuum fror the target, and the evaluation of a liquid metall target. Aspects concerning heat transfer, theory of strength of materials, neutron physics and safety have been considered.
